that ax-15 , behind cummin's.
3.9L , 50 lbs more torque, there, may be ok.
when buying custom mod. cars this is all normal.
1: nobody can fix your car, due to its not stock.
2: get stranded on the road, far from home and nobody will wont to touch it..
3: finding out just what the hacker did to make it work, now that takes alive human to do that... for sure.
hacker=modder=custom jeep.
you may need to go to jeep.com
and look at every front pinon shaft ever used
on the ax-15
my guess just 1.
it's too short because you have 3.9L cummins to Ax-15 adapter
there, and the mod guy, just ignored this.??? no photos presented by you.
my guess, (wild)
is it's this?
